ttJl-CIFICATQN termine part of Letters Patent No. 307,333, dated October 28, 1884.

Application tiled December 1T, 1853. (Model.)

'o a/Z 'lL/71,0111, it may concern:

Be it known that I, CHARLns Ricrmnns, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Anti-Friction Bearings and Bushings, of which improvements the following is a specification.

My invention relates to bearings of the io class in which metals of sufiicient strength and hardness to provide proper support to the `moving members which bear upon them, and` to be exempt from undue wear, are combined with a material possessing lubricating properi 5 ties-as graphite or compounds thereof-in order to provide a self-lubricating bearingsurface.

The object of my invention is to simplify and economize the construction of bearings of 2o such character, and to enable the lubricating material to be conveniently and securely located and maintained in position and disposed as desired over the area of bearing-surface.

To this end my improvements consist in a metallic bearing-plate having a series of opensided recesses'or depressions in' its bearingface adapted to receive a lubricant, and projections on its opposite face adapted to engage the metal of an inclosing casing or support;

3o also, in the combination of a bearing-plate, as specified, a filling of lubricating material in sorted inthe recesses thereof, and a casing, also, in the combination of two or more bearing-plates, as specified, and a illing of lubrieating material inserted in the recesses thereof; also, in the combination of two or more bearingplates, as specified, a filling of lubricating materiahand a casing inclosing and uniting the bearing-plates.

4o rIhc improvements claimed are hereinafter more fully set forth.

In the accompanying drawingsdfigure lis an end View in elevation of a continuous bearingplate embodying my invention; Fig. 2, a side View of the same; Fig. 3, an end View in elevation of a segmental bearing-plate; Fie'. 4, a side view of the same; Fig. 5, a transverse section, atthelinexaiofFig. 6, through a bearing or bushing having a series of bearing- 5o plates similar to those of Figs. 1 and 2; Fig.

G, an axial section through the same; Fig. 7,

a transverse section, at the line y 3/ of Fig. S, through a bearing or bushing having a series of bearing `-`plates similar to those of Figs. 3 and 4; and Fig. S, an axial section through 55 the same.

To carry ont my invention I forni of any suitable metal of sufficient strength and hardness to constitute the bearing or support of al moving member in a mechanical structure a 6o bearing-plate, l, having an inner bearing-suiface conforming throughout to the surface of the shaft, stem, or other member with which it is designed to be ,in contact when in use.

A series of recesses or slots, 2, is formed in the bearing-surface of the plate l, said recesses extending from thebeariiig-surface toward the periphery of the plate and across the plate7 thereby presenting a clear opening on three sides-to wit, the bearing-surface and the two 7o sides of the plate.

The recesses 2, which are designed to receive a filling of solid lubricating material in a compressed condition-as, for example, graphite-may be of any desired form and number, being preferably beveled or tapered inwardly, as shown, in order to more firmly retain the filling placed therein, and the in- Sertion and compression to any desired degree of the lubricant in the recesses can be readily 8o and perfectly accomplished, as the recesses are open and unobstructed on their tops and sides. One or more ribs or projections, 3, are formed upon the outer surface of the plate l; or, as a mechanical equivalent thereof, depres- 8 5 sions or indentations may he formed in said surfaces, in order to enable the plate to be engaged and firmly held by the metal of a casing or support, 4, cast around it, said casing serving to close the sides of the recesses 2 and form 9o the lateral boundary of the lubricant therein, and providing means for attaching the pla-tel to the member of the machine which it carries or on which it is fixed, as the case may be, as l also for uniting a series of two or more plates 9 5 in a bearing or bushing, as presently to be described.

The hearing-plate shown in Figs. 3 and 4,' which is designed for open or longitudinally splitor' divided bearings or bushings, differs roo having its recesses filled with lubricating ma' terial 5, (shown in solid black in the drawings,) is inclosed in a suitable casing, as the hub of a loose pulley, or a plumber-block or hanger, or a socket adapted to be fitted in such or analogous devices, and may be einployed either singly or in combination with one or more similar plates abutting at their sides one against another and fitting in a com` inon inclosing-casing; and in some instances it may be desirable to alternate plain bearing plates,or plates unprovided with recesses containing lubricant, with the plates l, before described.

Figs. 5 and fi illustrate a cylindrical bearing or bushing composed of a series of bearingplates,l, the recesses of which are packed with a lubricant filling, 5, and which are placed side by side and united by and inclosed within a casing7 4, cast around their peripheries and around the outer sides of the end plates ot' the series. The projections 3 of the plates are embedded in and the plates thereby irml y held by the metal ofthe casing, and the lubricant 5 is incased on every side except on the bearing-surface. The plates are by preference arranged, as shown, so that the filling of each recess shall abut against the metal between the recesses ou the adjacent plates, and the metal and lubricant are thereby disposed alternately throughout the area of the bearing surface. A senii-cylindrical bearing of similar construction is shown in Figs. 7 and S.

l ani aware that j ournal-bearings having recesses iilledwith graphite, asbestus, or softinetal alloys in their bearingsurfaces were known prior to my invention, and am further aware that a bearing having a continuous skeleton frame provided wit-l1 openings for the reception of soft metal, and having a casing cast around its outer surface, is not new. I therefore disclaim, broadly, a graphite fillin for a bearing, as also the combination, with a bearing, of a frame for containing a softer material.

I claim herein as my inventionl. A metallic bearing-plate having a series otl open sided recesses adapted to receive a filling of lubricating material on its bearingface, and a rib or projection on its opposite face, substantially as set forth.

2. Theeoinbination of a metallic bearingplate having a series of open-sided recesses on its bearingi'ace, a filling of lubricating material inserted in said recesses,and an inc-losingcasing, substantially as set forth.

3. The combination, in a bearing or bushing, ot' two or more metallic bearing -plates, each having a series of recesses in its bearing-face tilled with lubricating material, said bearingplates being united with their sides abutting one againstthe other, substantially as set forth.

4. The combination, in a bearing or bushing, of two or more metallic bearing-plates, each having a series of recesses in its bearing-face filled with lubricating material, said plates abuttingl at their sides. and an inclosing-cas ing cast around and uniting the bearing-plates, substantially as set forth.
